文摘

The work focuses on Ground Source Heat Pump in mild climates. Yearly simulations of GSHP are carried out for 3 different building load profiles. The effects of using pure water or water-glycol mixture have been investigated. Two heat pump technologies have been compared. Total energy costs of the systems have been evaluated.
